I think newer sendmails takes a -B option of 7BIT, or 8BITMIME. Check your sendmail man pages. Test it on the command line. Fix it by copying the sendmail lines from your RT_Config.om to your RT_SiteConfig.pm, and changing them there (and, then restarting apache...)

I have narrowed down the problem to the e-mail headers that RT generates. But I am clueless as to why this is a problem. We are an all-Windows shop, except for one ubuntu 8.10 server that runs RT 3.8 under Apache 2. For mail, it uses Postfix, and routes all mail to our local Exchange server (Exchange 2003 under Windows Server 2000). For e-mail that RT sends to recipients inside our domain, it all works well. But we have some contractors who need to receive e-mail from RT on certain events, and these contractors have addresses outside our network. But the mail is never delivered. After much experimentation, I narrowed the problem down to the "Content-Transfer-Encoding: 8bit" header. If that header is present, e-mail does not get delivered outside our network (e.g. to gmail.com, yahoo.com, anywhere); if that header is absent, e-mail goes through fine. syslog tells me nothing useful: No matter what, it reports "mail queued for delivery", which I presume is coming from the Exchange server. Now, I know this is not an RT problem, because I reproduced the problem consistently at the ubuntu command line by manually invoking sendmail. But a) I wonder if that header is required by RT, or if an alternative (base64?) could be used instead; and b) Maybe I'll get lucky and someone on the list will know a solution anyhow.
